Hey,
I have got your points from project description. So, you want to set restriction on uploading function based on packaging/membership option your users are using.
We are experts on making plugins, themes for WordPress. We have made over 500+ sites including very high budget projects from very basic website to large booking sites, listing/directory sites, merchant sites, auction sites, betting sites etc
YES, Keep faith on us, surely we will make your goal real :) Looking for close discussion and awarding us the project.
Thanks,
Suman C.
